Answer 1

Answer:

there are 5 Rs. 10 notes and 4 Rs. 50 notes

Step-by-step explanation:

Let the number of Rs. 50 notes be x

APQ:

10(x+1)+50x=250

Or

60x=240

Or

x=4

so there are 5 Rs. 10 notes and 4 Rs. 50 notes

Answer 2

Step-by-step explanation:

let that:

Rs 10 note = m

Rs 50 note = n

according to question

10m + 50n = 250 ......(1)

m - n = 1 ......(2)

Now

m = 1 + n

put value of m in (1)

10(1 + n) + 50n = 250

10 + 10n + 50n = 250

60n = 250 - 10

60n = 240

n = 240

60

n = 4

put vale of n in (2)

m + 4 = 1

m = 1+ 4

m = 5

hence solved
